Hi all !
I would like to have the possibility to introduce dynamic constraints at the time slice level. This would be useful , for example , to implement ramp-up and ramp-down constraints .
To my (limited) knowledge, currently the dynamic constraints operate at a time period level. Is it possible to extend them and make them also work at a time slice level as well, in the same manner as they are currently implemented at the time period level?
One possible complication would be how to initialise the variables introduced in the constraint. I guess that can be done in the same way as we initialise a variable in a growth/dynamic constraint.
One idea can be that the initial value of the variable in time slice 1 in year t is the value of the same variable in the last time slice n in year t-1 (in the order in which the time slices and milestone years are defined by the user). In this way, the constant that the user provides can be used to initialise the variable in the first time slice in the first year.
Or, there is already a way to introduce a dynamic constraint at a time slice level ?
Thanks a lot,
Vangelis
